CSS：使用宽度百分比定位子表？

Question

Page content, CSS Stylesheet

当您访问页面内容链接时，请获取下面的示例代码并提交。您会注意到子表source_code 并没有一直向右延伸。如果我将width: 100% 添加到syntax_table 类中，它可以解决问题，但source_code 表向右对齐，我无法让它向左移动。

我花了大约 2 个小时试图修复它，我现在需要一些帮助。

这里是一些 C# 示例代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;

namespace Test1
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }

        /// <summary>
        /// Calculate method.
        /// </summary>
        /// <param name="sender">Sender</param>
        /// <param name="e">Event Arguments</param>
        private void btnCalculate_Click(object sender, RoutedEventArgs e)
        {
            double weight;
            int heightf, heighti;

            Double.TryParse(this.txtWeight.Text, out weight);
            Int32.TryParse(this.txtHeightF.Text, out heightf);
            Int32.TryParse(this.txtHeightI.Text, out heighti);

            if (!(heightf >= 1))
                MessageBox.Show("A person is at least 1 foot tall.");
            else if (!(weight >= 1.0))
                MessageBox.Show("A person cannot weigh nothing.");
            else if (heightf >= 12)
                MessageBox.Show("A person is not taller than 12 feet.");
            else
            {
                double kg = weight * 0.45359237;
                int height = heighti + (heightf * 12);
                double bmi = weight / (height * height) * 703;
                double gbmi = Math.Round(bmi, 1);
                this.txtBMI.Text = bmi.ToString("n1");
            }
        }
    }
}

Answer 1

那是因为 .syntax_table 上的 2 个表格单元格会自行调整大小，您的浏览器会猜测。您至少需要设置包含 line_numbers 的表格单元格的宽度

<table class="syntax_table">
     <tr>
           <td class="lines"><table class="line_numbers">...</table></td>
           <td><table class="source_code">...</table></td>
     </tr>
</table>

样式

.source_code { width: 100%; } // add this to give source_code full width of it's cell
.lines { width: 50px } // or set to a percentage, then .code should take up the rest
